Japanese Patent Application No. 2014-084355 filed on Apr. 16, 2014,
Japanese Patent Application No. 2014-084359 filed on Apr. 16, 2014,
Japanese Patent Application No. 2014-084362 filed on Apr. 16, 2014,
and Japanese Patent Application No. 2014-084371 filed on Apr. 16,

BACKGROUND
[0002] 1. Field of the Invention
[0003] One or more embodiments of the present invention relate to a
grommet and a wire harness.
[0004] 2. Description of the Related Art
[0005] As an example of the grommet and the wire harness,
JP-A-2013-132167, for example, discloses a non-through type grommet
that has a protector accommodating a wire harness and a grommet
base portion having a protector accommodation portion accommodating
the protector and is attached to a grommet accommodation recess
portion formed on a door panel of a vehicle. This grommet has a
clamp insertion opening, a first water stopping lip and a second
water stopping lip on the back surface side of the grommet base
portion, and has a clamp engaging with the door panel on the bottom
surface of the protector. The grommet protrudes so that the clamp
can engage with the door panel from the clamp insertion opening
when the protector is accommodated in the protector accommodation
portion.
[0006] As another example of the grommet and the wire harness,
JP-A-2011-024280, for example, discloses a grommet body as a
sealing member applied to a wire harness which sealing member is
provided with a reinforcing member formed of a metal material and
where a through hole for fixing to a counterpart member is formed
and a flat portion formed of an elastic material, molded integrally
with the reinforcing member and where the reinforcing member is
embedded with the through hole being exposed, and holds the gap
with a counter part member watertight by coming into contact with
the counter part member.
SUMMARY
[0007] In the grommet described in JP-A-2013-132167, for example,
since the clamp is disposed so as to be situated substantially in
the center of the grommet base portion, the pressing force at both
ends of the water stopping lip situated in a position relatively
away from the clamp tends to be relatively smaller than the
pressing force in the central part, and there is room for
improvement in water stopping performance in this regard.
[0008] For the grommet body described in JP-A-2011-024280, for
example, a structure is desired where it can be surely fixed to the
counterpart member even if an iron-plate-form reinforcing member
molded integrally with the flat portion formed of the elastic
material is not provided.
[0009] In the grommet described in JP-A-2013-132167, for example,
when the shape of the door panel side and the position of
engagement by the clamp differ among vehicle models or the like,
there is further room for improvement in versatility such that
there are cases where the overall shape of the grommet, such as the
clamp placement position and the clamp insertion opening position,
has be to changed according to the vehicle type.
[0010] For the grommet body described in JP-A-2011-024280, for
example, it is desired to appropriately deliver water stopping
performance even if the iron-plate-form reinforcing member molded
integrally with the flat portion formed of the elastic material is
not provided.

body.
[0031] In a seventeenth aspect of the present invention, there is
provided the grommet according to the fifteenth or sixteenth
aspect, wherein the protector includes a reinforcing wall portion
interposed between the protector base portion and the protector
cover portion with respect to the pressing direction of the
outer.
[0032] In an eighteenth aspect of the present invention, there is

interval therebetween with respect to the width direction, and
wherein the base portion side wall portions contact the respective
cover portion side wall portions.
[0033] In a nineteenth aspect of the present invention, there is
provided a wire harness including: an electric wire including a
connection portion is provided on an end portion of the electric
wire; and a grommet including: a grommet body formed of an elastic
body and including a lip portion, wherein in a state in which an
electric wire of a wire harness is passed inside the grommet body
and the grommet body is attached to an accommodation recess portion
formed on an attachment panel, the lip portion contacts a water
stopped surface defining the accommodation recess portion to stop
water between the grommet body and the water stopped surface; a
protector which is formed of a rigid body having rigidity higher
than that of the grommet body and which is accommodated in an
accommodation space portion formed in the grommet body in a state
in which the electric wire is passed; and an outer which presses
the lip portion toward the water stopped surface and fixes the
grommet body to the attachment panel in a state in which the
grommet body and the protector are sandwiched between the outer and
the water stopped surface, wherein the protector includes: a
protector base portion which forms a base surface opposing the
water stopped surface and having a shape along the water stopped
surface; and a protector cover portion which forms a wiring space
portion in which the electric wire is passed between the protector
cover portion and the protector base portion, and which forms a
flat surface on which the weather strip provided on the attachment
panel across the grommet body is placed with the grommet body being
interposed.
[0034] The present invention is not limited to the above-described
aspects, but various modifications are possible within the scope of
the claims. For example, in the above-described aspects, two or
more than two aspects may be combined.
[0035] The grommet and the wire harness according to one aspect of
the present invention produces the following advantageous effect:
For example, since the pressing force can be applied to the lip
portion in a comparatively wide area by the lip portion being
placed in the pressed region pressed by the outer, water can be
surely stopped between the water stopping surface and the water
stopped surface by the lip portion pressed against the water
stopped surface, so that water stopping performance can be
improved.
[0036] The grommet and the wire harness according to another aspect
of the present invention produces the following advantageous
effect: The protector side protruding portion of the protector is
fitted in the first grommet body side recess portion of the grommet
body from the side of the accommodation space portion, and the
outer side protruding portion of the outer is fitted in the second
grommet body side recess portion of the grommet body from the side
of the outer surface. And in the grommet and the wire harness,
since the fitting parts are provided adjacent to each other, the
rigidity of the part, where the outer is attached, of the grommet
body as an elastic body can be ensured by these fitting parts. As a
consequence, in the grommet and the wire harness, the grommet body
can be surely fixed to the attachment panel.
[0037] The grommet and the wire harness according to still another
aspect of the present invention produces the following advantageous
effect: The outer has fixing portions provided as a pair so as to
sandwich the grommet body with respect to the width direction, and
is fixed to the attachment panel through the pair of fixing
portions in a state in which the grommet body is sandwiched between
the outer and the water stopped surface. Thereby, in the grommet
and the wire harness, for example, even when the configuration of
the side of the attachment panel differs among vehicle models or
the like, by changing the configurations of the fixing portions of
the outer or the like structured separately from the grommet body,
the grommet body can be appropriately fixed to the attachment panel
without the overall configuration of the grommet being changed. As
a consequence, in the grommet and the wire harness, versatility can
be improved.
[0038] The grommet and the wire harness according to yet another
aspect of the present invention produces the following advantageous
effect: By pressing the lip portion toward the water stopped
surface by transmitting the pressing force from the outer to the
lip portion through the base surface of the protector base portion
while the electric wires are protected by the protector
accommodated in the grommet body, water can be appropriately
stopped at the gap with the water stopped surface. Further, in the
grommet and the wire harness, since the surface where the weather
strip provided on the attachment panel and the grommet body abut on
each other can be made flat by the flat surface of the protector
cover portion, water can be appropriately stopped at the gap with
the weather strip. As a consequence, the grommet and the wire
harness can appropriately deliver water stopping performance.

[0059] The grommet 1 of the present embodiment shown in FIG. 1 is
applied when a wire harness 2 laid on a vehicle 100 is laid over
two spaces separated by a door panel 101 or the like as an
attachment panel in the vehicle 100. The grommet 1 is closely
attached to the side of the door panel 101 with electric wires 3 of
the wire harness 2 being passed, thereby watertightly laying the
wire harness 2 on the door panel 101. Here, the door panel 101 is,
for example, an inner panel constituting a door 102 of the vehicle
100, and the two spaces separated by the door panel 101 or the like
are, for example, a vehicle interior space and a vehicle exterior
space. The grommet 1 is for laying the wire harness 2 from the
vehicle body of the vehicle 100 to the door 102 pivotably provided
on the vehicle body. The wire harness 2 to which the grommet 1 is
applied is provided with electric wires 3 where connectors 4 as
connection portions are provided on end portions, and the grommet
1. The wire harness 2 is, for example, a member that bundles into
an aggregate part a plurality of electric wires 3 used for power
supply and signal communication and connects the electric wires 3
to the devices at a time by the connectors 4 for connection between
devices mounted on the vehicle 100. For example, some of the
connectors 4 of the wire harness 2 are connected to connectors (not
shown) of various electronic devices such as a speaker, a switch
unit, a door lock unit and a power window motor attached to the
door 102, and other connectors 4 are connected to connectors (not
shown) of a wire harness on the vehicle body side. The grommet 1 of
the present embodiment is a grommet of a so-called non-through type
having no through holes through which the electric wires 3 pass on
the door panel 101. The grommet 1 is attached to an accommodation
recess portion 103 (see also FIG. 18, etc. described later) formed
from a hinge side end surface 101a of the door panel 101 of the
door 102 (typically, a vehicle front side end surface where the
door 102 is hinged to the vehicle body) to a side surface 101b on
the vehicle interior space side. On the surface of the grommet 1, a
weather strip 104 is laminated. In addition thereto, the wire
harness 2 may include various components such as exterior members
such as a corrugate tube, a resin tape and a protector, an
electrical junction box, and a fixture.
[0060] Specifically, the grommet 1 of the present embodiment is
provided with, as shown in FIGS. 2 and 3, the grommet body 10, the
protector 20 and the outer 30.
[0061] In the following description, the direction along the
pressing by the outer 30 will be called the pressing direction, one
of the two directions perpendicular to the pressing direction will
be called the first width direction, and the other will be called
the second width direction. These pressing direction, first width
direction and second width direction are perpendicular to one
another. As shown in FIG. 1, etc., in a state in which the grommet
1 is attached to the accommodation recess portion 103 of the door
panel 101, the pressing direction of the grommet 1 corresponds to
the vehicle front-back direction in a state in which the door 102
is closed, the first width direction of the grommet 1 corresponds
to the vertical direction, and the second width direction of the
grommet 1 corresponds to the vehicle width direction in a state in
which the door 102 is closed. When the grommet body 10, the
protector 20 and the outer 30 are described, unless otherwise
specified, these elements will be described by using the directions
in a state in which the grommet 1 is attached to the accommodation
recess portion 103.
[0062] The grommet body 10 is a sealing member that stops water at
the gap with the door panel 101 as an attachment panel as shown in
FIGS. 2, 3, 4, 5, 6 and 7. The grommet body 10 has a grommet base
portion 11, a tubular portion 12 and a lip portion 13, and these
are formed of an elastic body in an integrated manner. The grommet
body 10 is formed of a flexible elastic material with low rigidity
such as rubber or thermoplastic elastomer (for example,
ethylene-propylene-diene rubber [EPDM]). In the description of the
grommet body 10, FIG. 18 is also referred to as appropriate.
[0063] The grommet base portion 11 is a portion which can be
attached to the accommodation recess portion 103 and an inside of
which the electric wires 3 of the wire harness 2 are passed and
that is formed on the door panel 101 (see FIG. 1, etc.).
[0064] Here, as described above with reference to FIG. 1, the
accommodation recess portion 103 is formed from the hinge side end
surface 101a of the door panel 101 to the side surface 101 b in the
vehicle interior space. More specifically, as shown in FIG. 18, the
accommodation recess portion 103 is formed of a recessed portion on
the hinge side end surface 101a of the door panel 101. The
accommodation recess portion 103 is formed by the hinge side end
surface 101a of the door panel 101 being recessed along the
pressing direction so that the cross-sectional shape along a
surface perpendicular to the second width direction is
substantially inverted trapezoidal. The portion that defines the
accommodation recess portion 103 on the door panel 101 is a water
stopped surface 105 that is water-stopped by the grommet body 10.
The water stopped surface 105 includes a slanting wall portion 105a
forming the above-mentioned inverted trapezoidal shape and a flat
bottom portion 105b. The flat bottom portion 105b is formed in a
substantially rectangular shape and constitutes the bottom surface
of the accommodation recess portion 103, and the slanting wall
portion 105a is formed as a U-shaped tapered surface so as to
surround three sides of the flat bottom portion 105b (three sides
other than the side situated on the side of the side surface 101b).
The grommet body 10 is attached to the hinge side end surface 101a
of the door panel 101 in such a way that the grommet base portion
11 closes the accommodation recess portion 103.
[0065] Returning to FIGS. 2, 3, 4, 5, 6 and 7, the grommet base
portion 11 includes a grommet flat portion 11a, a grommet bulging
portion 11b, an accommodation space portion 11c and a tubular
portion connection portion 11d, and these are integrated so as to
be hollow as a whole. In the grommet base portion 11, the electric
wires 3 are passed in the hollow portion (accommodation space
portion 11c). In this example, in the grommet base portion 11, the
electric wires 3 are passed through the later-described protector
20 accommodated in the accommodation space portion 11c. The grommet
base portion 11 is formed so that the outer shape (the shape on a
surface perpendicular to the pressing direction) of the grommet
flat portion 11a and the grommet bulging portion 11b is
substantially similar to that of the above-described accommodation
recess portion 103 (see FIG. 18), and has a shape that can be
accommodated and attached in the accommodation recess portion 103.
Moreover, in the grommet base portion 11, the cross-sectional shape
of the grommet flat portion 11a and the grommet bulging portion 11b
along a surface perpendicular to the second width direction is
formed in a substantially inverted trapezoidal hollow form slightly
smaller than the accommodation recess portion 103 (see FIG. 18). In
the grommet base portion 11, the grommet bulging portion 11b
opposes the water stopped surface 105 with respect to the pressing
direction in a state in which the grommet base portion 11 is
accommodated in the accommodation recess portion 103 (see FIG.
18).
[0066] More specifically, the grommet flat portion 11a is a portion
that forms a flat surface 11e where the weather strip 104 (see FIG.
1) is placed. The grommet bulging portion 11b is a portion that
forms a water stopping surface 11f of the grommet base portion 11.
The water stopping surface 11f is a surface opposing the water
stopped surface 105 (see FIG. 18) that defines the accommodation
recess portion 103 in a state in which the grommet base portion 11
is attached to the accommodation recess portion 103. In other
words, the grommet bulging portion 11b forms the water stopping
surface 11f of a shape along the water stopped surface 105. The
grommet bulging portion 11b is formed in a shape corresponding to
the water stopped surface 105, in other words, a shape along the
water stopped surface 105 in a state in which the grommet base
portion 11 is attached to the accommodation recess portion 103. The
grommet bulging portion 11b includes a slanting wall portion 11g
and a flat bottom portion 11h so as to correspond to the slanting
wall portion 105a (see FIG. 18) and the flat bottom portion 105b
(see FIG. 18) of the water stopped surface 105. The flat bottom
portion 11h is formed in a substantially rectangular shape and
constitutes the bottom surface of the grommet bulging portion 11b,
and the slanting wall portion 11g is formed as a U-shaped tapered
surface so as to surround three sides of the flat bottom portion
11h (three sides other than the side situated on the vehicle
interior space side when the grommet base portion 11 is attached to
the accommodation recess portion 103). The grommet bulging portion
11b has a configuration that is continuous with the grommet flat
portion 11a on the side of the slanting wall portion 11g and bulges
from the grommet flat portion 11a in the pressing direction by the
slanting wall portion 11g and the flat bottom portion 11h, thereby
zoning the accommodation space portion 11c inside. In the grommet
bulging portion 11b, the slanting wall portion 11g opposes the
slanting wall portion 105a and the flat bottom portion 11h opposes
the flat bottom portion 105b in a state in which the grommet base
portion 11 is attached to the accommodation recess portion 103 (see
FIG. 18).
[0067] The accommodation space portion 11c is defined by the
grommet flat portion 11a and the grommet bulging portion 11b as a
hollow wiring space portion where the electric wires 3 can be laid
(see FIG. 6, etc.). In this example, the accommodation space
portion 11c functions as a space portion accommodating the
later-described protector 20, and the electric wires 3 are passed
through the protector 20. The accommodation space portion 11c is
closed on the side of the slanting wall portion 11g of the grommet
bulging portion 11b. On the other hand, in the accommodation space
portion 11c, the side of the remaining one side of the flat bottom
portion 11h (one side in the second width direction shown in FIG.
6) is open with respect to the second width direction, and this
functions as an insertion opening 11i through which the
later-described protector 20 is insertable into the accommodation
space portion 11c. That is, the grommet base portion 11 of the
grommet body 10 has the insertion opening 11i where the
later-described protector 20 is insertable into the accommodation
space portion 11c from one side. The above-described flat surface
11e is formed by the outer surface of the grommet flat portion 11a,
that is, by the surface opposite to the accommodation space portion
11c. The above-described water stopping surface 11f is formed by
the outer surface of the grommet bulging portion 11b, that is, by
the surface opposite to the accommodation space portion 11c.
[0068] On the grommet flat portion 11a, with respect to the second
width direction (see FIG. 6, etc.), a connection opening 11j is
formed on the side opposite to the side where the insertion opening
11i is formed. The connection opening 11j is open in the pressing
direction. The tubular portion connection portion 11d is formed on
an edge portion of the connection opening 11j. The tubular portion
connection portion 11d is formed as a rising portion protruding
from the flat surface 11e of the grommet flat portion 11a along the
pressing direction. To the tubular portion connection portion 11d,
the tubular portion 12 is connected.
[0069] The tubular portion 12 is an accordion tube where the
electric wires 3 of the wire harness 2 are passed. To one end of
the tubular portion 12, the tubular portion connection portion 11d
is integrally connected, and on the other end, a vehicle body side
grommet portion 12a connected to the vehicle side is provided. An
insertion space portion 12b (see FIG. 6, etc.) inside the tubular
portion 12 communicates with the accommodation space portion 11c of
the grommet base portion 11 through the connection opening 11j, so
that the electric wires 3 can be passed therethrough.
[0070] The lip portion 13 contacts the water stopped surface 105
that defines the accommodation recess portion 103 in a state in
which the electric wires 3 are passed inside the grommet base
portion 11 and the grommet base portion 11 is attached to the
accommodation recess portion 103 formed on the door panel 101,
thereby being capable of stopping water between the grommet body 10
and the water stopped surface 105. The lip portion 13 is formed so
as to protrude from the water stopping surface 11f of the grommet
base portion 11, and as shown in FIG. 18, etc., comes into contact
with the water stopped surface 105 to thereby stop water between
the water stopping surface 11f and the water stopped surface 105
and hold water-tightness.
[0071] The lip portion 13 of the present embodiment includes an
outside lip portion 13a as a first lip portion and an inside lip
portion 13b as a second lip portion (see FIGS. 6 and 7). As shown
in FIG. 7, etc., the outside lip portion 13a is formed
substantially linearly along the first width direction on the water
stopping surface 11f of the grommet base portion 11. The outside
lip portion 13a is formed so as to extend from the edge portion on
one side to the edge portion on the other side of the water
stopping surface 11f in the first width direction while both end
portions are provided on both edge portions of the water stopping
surface 11f in the first width direction. The inside lip portion
13b is formed on the insertion opening 11i side of the outside lip
portion 13a with respect to the second width direction. That is, in
the lip portion 13, with respect to the second width direction, the
outside lip portion 13a is disposed on the vehicle exterior space
side, and the inside lip portion 13b is disposed on the vehicle
interior space side. The inside lip portion 13b is formed in a
substantially U shape on the water stopping surface 11f. The inside
lip portion 13b is formed so as to extend from the edge portion on
one side to the edge portion on the other side of the water
stopping surface 11f in the first width direction while both end
portions are provided on both edge portions of the water stopping
surface 11f in the first width direction and the central portion in
the first width direction is bent so as to protrude toward the
outside lip portion 13a. The outside lip portion 13a typically
functions as a water stopping line that directs a large water flow
trying to enter the vehicle interior space side from the vehicle
exterior space side, to the vehicle exterior space side. The inside
lip portion 13b typically functions as a final water stopping line
for the vehicle interior space in the grommet body 10. The outside
lip portion 13a and the inside lip portion 13b of the present
embodiment are both formed, as shown in FIG. 6, etc., so as to be
hollow while the shape of the cross section along a surface
perpendicular to the first width direction is substantially
triangular. The position of placement of the lip portion 13 will be
described later in detail.
[0072] In the above-described grommet base portion 11, a drainage
hole 11k for drainage (see FIGS. 4 and 7, etc.) is formed in a part
which is the lower side in the vertical direction (one side in the
first width direction) on the grommet flat portion 11a in a state
in which the grommet body 10 is attached to the accommodation
recess portion 103. The drainage hole 11k is situated between the
outside lip portion 13a and the inside lip portion 13b with respect
to the second width direction.
[0073] The protector 20 is, as shown in FIGS. 2, 3, 8 and 9, a
protective member that is accommodated in the accommodation space
portion 11c formed inside the grommet base portion 11 of the
grommet body 10 in a state in which the electric wires 3 are
passed, and protects the electric wires 3. The protector 20 has a
protector base portion 21, a protector cover portion 22, a wiring
space portion 23 and a bundle portion 24, and these are formed, in
an integrated manner, as a rigid body having rigidity higher than
that of the grommet body 10. The protector 20 is formed of, for
example, a synthetic resin material such as polypropylene (PP)
having rigidity higher than that of the grommet body 10. In the
description of the protector 20, FIGS. 13 and 18, etc. will also be
referred to as appropriate.
[0074] The protector 20 is formed so as to be hollow as a whole by
the protector base portion 21 and the protector cover portion 22
being integrated with each other, and the electric wires 3 are
passed in the hollow portion (the wiring space portion 23 [see
FIGS. 13 and 18, etc.]). The protector 20 is formed so that the
outer shape of the protector base portion 21 and the protector
cover portion 22 (the shape on a surface perpendicular to the
pressing direction) is substantially similar to that of the
above-described accommodation space portion 11c, and has a shape
that can be inserted and accommodated in the accommodation space
portion 11c. Moreover, in the protector 20, the cross-sectional
shape, along a surface perpendicular to the second width direction,
of the protector base portion 21 and the protector cover portion 22
is formed in a substantially inverted trapezoidal hollow form
slightly smaller than the accommodation recess portion 103,
specifically, formed in a substantially inverted trapezoidal hollow
form slightly smaller than the grommet flat portion 11a and the
grommet bulging portion 11b (see FIG. 18). In the protector 20, the
protector base portion 21 opposes and contacts the grommet bulging
portion 11b and the protector cover portion 22 opposes and contacts
the grommet flat portion 11a (see FIG. 18) in a state in which the
protector 20 is accommodated in the accommodation space portion
11c.
[0075] More specifically, the protector base portion 21 is a
container-like member that forms a base surface 21a of a shape
along the water stopped surface 105 (see FIG. 18) in a state in
which the protector 20 is accommodated in the accommodation space
portion 11c and the grommet base portion 11 is attached to the
accommodation recess portion 103. The protector base portion 21 of
the present embodiment has a shape along the grommet bulging
portion 11b. The protector base portion 21 is formed in a shape
corresponding to the water stopped surface 105 and the grommet
bulging portion 11b, in other words, in a shape along the water
stopped surface 105 and the grommet bulging portion 11b. The
protector base portion 21 includes, as shown in FIG. 18, etc., a
slanting wall portion 21b and a flat bottom portion 21c so as to
correspond to the slanting wall portion 105a and the slanting wall
portion 11g, and the flat bottom portion 105b and the flat bottom
portion 11h. The flat bottom portion 21c is formed in a
substantially rectangular shape and constitutes the bottom surface
of the protector base portion 21, and the slanting wall portion 21b
is formed as a U-shaped tapered surface so as to surround three
sides of the flat bottom portion 21c (three sides other than the
side situated on the vehicle interior space side when the grommet
base portion 11 is attached to the accommodation recess portion
103). In the protector base portion 21, the surface opposite to the
flat bottom portion 21c is an open surface. In the protector base
portion 21, the slanting wall portion 21b opposes and contacts the
slanting wall portion 11g and the flat bottom portion 21c opposes
and contacts the flat bottom portion 11h in a state in which the
protector 20 is accommodated in the accommodation space portion 11c
(see FIG. 13, etc.).
[0076] The protector cover portion 22 is a lid-like portion that
forms a flat surface 22a where the weather strip 104 is placed
through the grommet flat portion 11a (see FIG. 18, etc.). The
protector cover portion 22 forms the wiring space portion 23 where
the electric wires 3 are passed between it and the protector base
portion 21 and forms the flat surface 22a. The flat surface 22a is
a surface where the weather strip 104 provided on the door panel
101 across the grommet body 10 is placed with the grommet flat
portion 11a of the grommet body 10 being interposed. The protector
cover portion 22 is formed in a plate form, and one side thereof is
integrally connected to the protector base portion 21 through a
hinge portion 22b and the like. Thereby, the protector cover
portion 22 can be opened and closed so as to cover the open surface
of the protector base portion 21, and defines the wiring space
portion 23 between it and the protector base portion 21 by being
closed.
[0077] The wiring space portion 23 is defined by the protector base
portion 21 and the protector cover portion 22 as a hollow wiring
space portion where the electric wires 3 can be laid (see FIG. 18,
etc.). As shown in FIG. 8, etc., the side of the wiring space
portion 23 opposite to the slanting wall portion 21b of the
protector base portion 21 is open with respect to the second width
direction, and the opening functions as an insertion opening 25
where the electric wires 3 are insertable into the wiring space
portion 23. The end portion of the protector base portion 21
opposite to the slanting wall portion 21b is bent toward the side
away from the protector cover portion 22 along the pressing
direction to constitute a bent portion 21d. The insertion opening
25 is formed as a gap between the bent portion 21d of the protector
base portion 21 and the protector cover portion 22. Thereby, the
protector 20 has a structure where the electric wires 3 are
insertable into the wiring space portion 23 through the insertion
opening 25. The side of the wiring space portion 23 on the side of
the protector base portion 21b of the protector base portion 21,
that is, the side of the wiring space portion 23 opposite to the
insertion opening 25 is open to the side of the protector cover
portion 22 with respect to the pressing direction, and the opening
functions as an insertion opening 26 where the electric wires 3 can
be passed. The protector cover portion 22 does not cover the entire
part of the open surface of the protector base portion 21 but an
opening is left on the side of the slanting wall portion 21b of the
protector base portion 21, and the opening is the insertion opening
26. The insertion opening 26 is formed in a position opposing the
insertion opening 11i of the grommet body 10 with respect to the
pressing direction in a state in which the protector 20 is inserted
and accommodated in the accommodation space portion 11c of the
grommet body 10 (see FIG. 13). Thereby, in the protector 20, the
electric wires 3 can be passed through the insertion opening 26 and
the insertion opening 11i between the side of the wiring space
portion 23 and the side of the insertion space portion 12b inside
the tubular portion 12. The above-mentioned base surface 21a is
formed of the outer surface of the protector base portion 21, that
is, of the surface opposite to the wiring space portion 23. The
above-mentioned flat surface 22a is formed of the outer surface of
the protector cover portion 22, that is, of the surface opposite to
the wiring space portion 23.
[0078] Moreover, the protector 20 has, as shown in FIG. 18, a
reinforcing wall portion 27 interposed between the protector base
portion 21 and the protector cover portion 22 with respect to the
pressing direction. In the present embodiment, the reinforcing wall
portion 27 is provided more than one in number. The reinforcing
wall portions 27 each include a base portion side wall portion 27a
provided on the protector base portion 21 and a cover portion side
wall portion 27b provided on the protector cover portion 22. The
base portion side wall portion 27a and the cover portion side wall
portion 27b are provided on both edge portions of the protector
base portion 21 and the protector cover portion 22 with respect to
the first width direction, respectively. The base portion side wall
portion 27a and the cover portion side wall portion 27b are
provided so as to rise along the pressing direction from the
protector base portion 21 and the protector cover portion 22,
respectively, and extend along the second width direction. Thereby,
the strength of the protector 20 in the pressing direction is
improved.
[0079] More specifically, the reinforcing wall portions 27 include,
as shown in FIG. 18, a pair of base portion side wall portions 27a
provided on the protector base portion 21 and opposing each other
with an interval therebetween with respect to the first width
direction perpendicular to the pressing direction and a pair of
cover portion side wall portions 27b provided on the protector
cover portion 22 and opposing each other with an interval
therebetween with respect to the first width direction. The pair of
base portion side wall portions 27a and the pair of cover portion
side wall portions 27b are arranged such that the base portion side
wall portions 27a contact the respective cover portion side wall
portions 27b. In this example, the reinforcing wall portion 27
further includes another base portion side wall portion 27a on one
side in the first width direction (in FIG. 18, the side which is
the upper side from the viewer's side and the side where the
above-mentioned hinge portion 22b [see FIG. 8] is provided). On one
side of the reinforcing wall portion 27 in the first width
direction, the first base portion side wall portion 27a, the cover
portion side wall portions 27b and the second base portion side
wall portion 27a are arranged in this order from the outside toward
the inside in the first width direction and contact one another. On
the other hand, on the other side of the reinforcing wall portion
27 in the first width direction, the cover portion side wall
portions 27b and the base portion side wall portions 27a are
arranged in this order from the outside toward the inside in the
first width direction and contact one another.
[0080] Returning to FIGS. 2, 3, 8 and 9, the bundle portion 24 is a
portion that bundles the electric wires 3 passed in the wiring
space portion 23 with a bundling band or the like and fixes them.
The bundle portion 24 is formed so as to protrude from the bent
portion 21d of the protector base portion 21.
[0081] The outer 30 is, as shown in FIGS. 2, 3, 10 and 11, a fixing
member structured separately from the grommet body 10 in order to
fix the grommet body 10 to the door panel 101. The outer 30 has a
body portion 31 and a pair of fixing portions 32 and 33 and these
are formed, in an integrated manner, as a rigid body having
rigidity higher than that of the grommet body 10. The outer 30 is
formed of, for example, a synthetic resin material such as
polypropylene (PP) having rigidity higher than that of the grommet
body 10. In the description of the outer 30, FIG. 18 will also be
referred to as appropriate.
[0082] The outer 30 presses the lip portion 13 of the grommet body
10 toward the water stopped surface 105 and fixes the grommet body
10 to the door panel 101 in a state in which the grommet base
portion 11 of the grommet body 10 and the protector 20 are
sandwiched between the outer 30 and the water stopped surface
105.
[0083] More specifically, the body portion 31 is a portion formed
along the first width direction and sandwiching the grommet body 10
and the protector 20 between it and the water stopped surface 105
in a state in which the outer 30 fixes the grommet body 10 to the
door panel 101 (see FIG. 18, etc.). The body portion 31 is formed
in a joist form along the first width direction, and a
predetermined part thereof is reinforced by a rib or the like. The
fixing portions 32 and 33 are provided as a pair so that they are
situated so as to sandwich the grommet base portion 11 of the
grommet body 10 with respect to the first width direction in a
state in which the outer 30 fixes the grommet body 10 to the door
panel 101. The fixing portions 32 and 33 are provided on both end
portions of the body portion 31 with respect to the first width
direction. More specifically, the fixing portions 32 and 33 are
formed so as to protrude from both end portions of the body portion
31 toward one side in the second width direction, and forms a
fitting space portion 34 in a gap with the body portion 31 by
protruding. The fitting space portion 34 is a space portion three
sides of which are surrounded by the body portion 31 and the pair
of fixing portions 32 and 33. In a state in which the outer 30
fixes the grommet body 10 to the door panel 101, the tubular
portion connection portion 11d of the grommet base portion 11 and a
part of the tubular portion 12 are fitted in the fitting space
portion 34 from the side of the flat surface 11e of the grommet
base portion 11 (see FIG. 15, etc.). In this state, the outer 30 is
in a positional relationship such that the pair of fixing portions
32 and 33 sandwich the tubular portion connection portion 11d and
the like with respect to the first width direction. Then, the outer
30 is fixed to the door panel 101 through the pair of fixing
portions 32 and 33. On the fixing portions 32 and 33 of the present
embodiment, bolt holes 32a and 33a for bolting are formed,
respectively. Fastening bolts 32b and 33b are inserted into the
bolt holes 32a and 33a and inserted into bolt holes 101c and 101d
formed on the hinge side end surface 101a of the door panel 101,
respectively, and the tips thereof are screwed to fastening nuts
101e and 101f, whereby the outer 30 is fixed to the hinge side end
surface 101a by the bolting (see FIG. 18).
[0084] The grommet body 10, the protector 20 and the outer 30
structured as described above are assembled to one another as shown
in FIGS. 1, 2, 12, 13, 14, 15 and 16, thereby constituting the
grommet 1 as a whole. That is, in the grommet 1, the protector 20
where the electric wires 3 are passed in the wiring space portion
23 is accommodated in the accommodation space portion 11c of the
grommet body 10. Moreover, in the grommet 1, the outer 30 is
attached to the grommet body 10 in a positional relationship such
that the tubular portion connection portion 11d of the grommet base
portion 11 and the like are fitted in the fitting space portion 34.
Further, in the grommet 1, as shown in FIGS. 17 and 18, the grommet
base portion 11 of the grommet body 10 is attached to the
accommodation recess portion 103. And in the grommet 1, the pair of
fixing portions 32 and 33 are bolted to the door panel 101 in a
state in which the grommet base portion 11 of the grommet body 10
and the protector 20 are sandwiched between the body portion 31 of
the outer 30 and the water stopped surface 105. As a consequence,
the grommet 1 is fixed to the door panel 101 in a state in which
the lip portion 13 of the grommet body 10 is pressed toward the
water stopped surface 105 by the outer 30. Thereby, the grommet 1
is prevented from separating from the vehicle 100 and is surely
fixed to the accommodation recess portion 103 of the door panel
101.
[0085] In this case, in the grommet 1 of the present embodiment, as
shown in FIGS. 13, 14 and 15, etc., a first grommet body side

between the outer 30 and the lip portion 13 with respect to the
pressing direction in a state in which the grommet 1 is attached
and fixed to the accommodation recess portion 103 through the outer
30, and forms a layer structure together with the grommet body 10.
More specifically, in the protector 20, at least the protector
cover portion 22 and a part of the protector base portion 21, in
this example, the end portion on the side of the insertion opening
26 are interposed between the body portion 31 of the outer 30 and
the lip portion 13 with respect to the pressing direction, and form
the layer structure together with the grommet body 10. That is, in
the grommet 1, the grommet flat portion 11a (the flat surface 11e)
of the grommet base portion 11, the protector cover portion 22 (the
flat surface 22a) of the protector 20, the wiring space portion 23,
the protector base portion 21 (the base surface 21a) of the
protector 20, the grommet bulging portion 11b (the water stopping
surface 11f) of the grommet base portion 11 and the lip portion 13
form the layer structure in this order between the body portion 31
of the outer 30 and the water stopped surface 105 with respect to
the pressing direction. Thereby, in the grommet 1, the protector 20
functions as a pressing force transmitting portion that transmits
the pressing force from the outer 30 to the lip portion 13 or a
pressing portion that presses the lip portion 13.
[0096] In the grommet 1 structured as described above, in a state
in which it is attached and fixed to the accommodation recess
portion 103 of the door panel 101 through the outer 30, the outer
30 presses the lip portion 13 of the grommet body 10 toward the
water stopped surface 105, whereby the lip portion 13 is pressed
against the water stopped surface 105 to be deformed elastically.
More specifically, the outside lip portion 13a is elastically
deformed and comes into close contact by being pressed toward the
water stopped surface 105 through the protector 20 by the outer 30,
and the inside lip portion 13b is elastically deformed and comes
into close contact by being pressed toward the water stopped
surface 105 through the protector 20 by the outer 30 and the
weather strip 104. As a consequence, in the grommet 1, the lip
portion 13 stops water between the water stopping surface 11f and
the water stopped surface 105, so that water intrusion from the
vehicle exterior space side to the vehicle interior space side of
the grommet 1 can be suppressed.
[0097] According to the grommet 1 described above, the grommet body
10, the outer 30 and the protector 20 as the rigid body portion are
provided, and at least a part of the lip portion 13 is placed in
the pressed region 35 pressed by the outer 30.
[0098] According to the wire harness 2 described above, the
electric wires 3 where the connectors 4 are provided on the end
portions and the above-described grommet 1 are provided, and at
least a part of the lip portion 13 is placed in the pressed region
35 pressed by the outer 30.
[0099] Therefore, in the grommet 1 and the wire harness 2, for
example, since the pressing force can be substantially uniformly
applied to the lip portion 13 in a comparatively wide area by the
lip portion 13 being placed in the pressed region 35 pressed by the
outer 30, water can be surely stopped between the water stopping
surface 11f and the water stopped surface 105 by the lip portion 13
pressed against the water stopped surface 105, so that water
stopping performance can be improved.
[0100] Moreover, in this case, in the grommet 1 and the wire
harness 2, since the lip portion 13 is hollow and elastically
deformed with ease, for example, compared with a lip portion that
is dense inside, the lip portion 13 can be crushed so as to be in
contact with the water stopped surface 105 with a smaller pressing
force. As a consequence, in the grommet 1 and the wire harness 2,
since the reaction force that the outer 30 receives from the lip
portion 13 can be suppressed to a relatively small one when the lip
portion 13 is pressed, for example, even when the outer 30 is
formed of a resin material having rigidity lower than that of
metal, strength sufficient for receiving the reaction force can be
ensured. That is, in the grommet 1 and the wire harness 2, since
the outer 30 can be formed of a resin material having relatively
low rigidity, for example, weight increase can be suppressed, and
even when the outer 30 differs among vehicle models, manufacture is
easy.
[0101] More specifically, according to the grommet 1 and the wire
harness 2 described above, the outer 30 has the fixing portions 32
and 33 provided as a pair so as to sandwich the grommet body 10
with respect to the first width direction perpendicular to the
pressing direction and is fixed to the door panel 101 through the
pair of fixing portions 32 and 33, and the lip portion 13 is placed
in an area within the pressed region 35 and between the pair of
fixing portions 32 and 33 with respect to the first width
direction. Therefore, in the grommet 1 and the wire harness 2,
since a part of the lip portion 13 is placed in the area between
the pair of fixing portions 32 and 33 where the force of pressing
by the outer 30 tends to be comparatively large, a larger pressing
force can be appropriately applied to the lip portion 13, so that
water stopping performance can be further improved.
[0102] Further, according to the grommet 1 and the wire harness 2
described above, the grommet body 10 has the grommet base portion
11 attachable to the accommodation recess portion 103 where the
electric wires 3 are passed and that is formed on the door panel
101, and the lip portion 13 has the outside lip portion 13a and the
inside lip portion 13b. The outside lip portion 13a is formed so as
to protrude from the water stopping surface 11f, and the entire
part thereof is placed in the pressed region 35. The inside lip
portion 13b is formed so as to protrude from the water stopping
surface 11f, and at least part thereof is placed in the pressed
region 35 and another part thereof is placed in the placement
region 104a of the weather strip 104. Therefore, in the grommet 1
and the wire harness 2, the outside lip portion 13a can be surely
pressed toward the water stopped surface 105 by the outer 30 so as
to be elastically deformed and in close contact, and the inside lip
portion 13b can be surely pressed toward the water stopped surface
105 by the outer 30 and the weather strip 104 so as to be
elastically deformed and in close contact. As a consequence, in the
grommet 1 and the wire harness 2, water can be surely stopped
between the water stopping surface 11f and the water stopped
surface 105 by the outside lip portion 13a and the inside lip
portion 13b.
[0103] Further, according to the grommet 1 and the wire harness 2
described above, the protector 20 is provided so as to be formed of
a rigid body having rigidity higher than that of the grommet body
10 as described above, is accommodated in the accommodation space
portion 11c formed in the grommet body 10 in a state in which the
electric wires 3 are passed, and constitutes a rigid body portion,
and the protector 20 is interposed between the outer 30 and the lip
portion 13 with respect to the pressing direction and forms a layer
structure together with the grommet body 10. Therefore, in the
grommet 1 and the wire harness 2, the pressing force from the outer
30 is transmitted to the lip portion 13 through the grommet body 10
and the protector 20 as the rigid body portion, more specifically,
through the grommet flat portion 11a, the protector cover portion
22, the protector base portion 21 and the grommet bulging portion
11b in this order, so that the lip portion 13 can be pressed toward
the water stopped surface 105. As a consequence, in the grommet 1
and the wire harness 2, since the pressing force from the outer 30
can be more uniformly transmitted to the lip portion 13, the water
stopping performance in the entire part of the lip portion 13 can
be made substantially uniform, so that water stopping performance
can be improved also in this regard.
[0104] According to the grommet 1 described above, the grommet body
10, the protector 20 and the outer 30 are provided, the grommet
body 10 has the first grommet body side recess portion 11l formed
on the side of the accommodation space portion 11c and the second
grommet body side recess portion 11m formed on the outer surface so
as to be adjacent to the first grommet body side recess portion
11l, the protector 20 has the protector side protruding portion 21e
fitted in the first grommet body side recess portion 11l in a state
in which the protector 20 is accommodated in the accommodation
space portion 11c, and the outer 30 has the outer side protruding
portion 36 fitted in the second grommet body side recess portion
11m in a state in which the grommet body 10 is fixed to the door
panel 101.
[0105] According to the wire harness 2 described above, the
electric wires 3 where the connectors 4 are provided on end
portions and the above-described grommet 1 are provided, the
grommet body 10 has the first grommet body side recess portion 11l
formed on the side of the accommodation space portion 11c and the
second grommet body side recess portion 11m formed on the outer
surface so as to be adjacent to the first grommet body side recess
portion 11l, the protector 20 has the protector side protruding
portion 21e fitted in the first grommet body side recess portion
11l in a state in which the protector 20 is accommodated in the
accommodation space portion 11c, and the outer 30 has the outer
side protruding portion 36 fitted in the second grommet body side
recess portion 11m in a state in which the grommet body 10 is fixed
to the door panel 101.
[0106] Therefore, in the grommet 1 and the wire harness 2, the
protector side protruding portion 21e of the protector 20 is fitted
in the first grommet body side recess portion 11l of the grommet
body 10 from the side of the accommodation space portion 11c, and
the outer side protruding portion 36 of the outer 30 is fitted in
the second grommet body side recess portion 11m of the grommet body
10 from the outer surface side. And in the grommet 1 and the wire
harness 2, since the fitting parts are provided adjacent to each
other, the rigidity of the part, where the outer 30 is attached, of
the grommet body 10 as an elastic body can be ensured by these
fitting parts. As a consequence, in the grommet 1 and the wire
harness 2, the position of the grommet body 10 can be prevented by
the outer 30 from being shifted with respect to the first width
direction and the second width direction while the outer 30 is
surely attached to the grommet body 10, so that the grommet body 10
can be surely fixed to the door panel 101. That is, in the grommet
1 and the wire harness 2, the protector side protruding portion 21e
and the outer side protruding portion 36 are fitted together in a
positional relationship such that the wall surface on the border
between the first grommet body side recess portion 11l and the
second grommet body side recess portion 11m of the grommet body 10
as an elastic body is sandwiched by the rigid bodies. As a
consequence, in the grommet 1 and the wire harness 2, since the
rigidity of the fitting parts can be ensured at the grommet body 10
as an elastic body, the grommet body 10 can be positioned on the
door panel 101 and fixed after firmly pressed down toward the water
stopped surface 105 by the outer 30. Moreover, in the grommet 1 and
the wire harness 2, since a part (the tubular portion connection
portion 11d of the grommet base portion 11, etc.) of the grommet
body 10 can be pressed toward the water stopped surface 105 by the
pair of stepped portions 37 of the outer 30, the grommet body 10
can be securely positioned on the door panel 101 and fixed also in
this regard.
[0107] More specifically, according to the grommet 1 and the wire
harness 2 described above, the protector side protruding portion
21e is formed along the pressing direction of the outer 30, the
outer side protruding portion 36 is formed along the first width
direction perpendicular to the pressing direction, and the
protector side protruding portion 21e and the outer side protruding
portion 36 adjacent to each other with a part of the grommet body
10 interposed therebetween along the pressing direction and the
second width direction perpendicular to the first width direction
in a state in which the protector 20 is accommodated in the
accommodation space portion 11c and the grommet body 10 is fixed to
the door panel 101 by the outer 30. Therefore, in the grommet 1 and
the wire harness 2, a structure can be easily realized in which the
protector side protruding portion 21e and the outer side protruding
portion 36 are fitted together in a positional relationship such
that the wall surface on the border between the first grommet body
side recess portion 11l and the second grommet body side recess
portion 11m of the grommet body 10 as an elastic body is sandwiched
by the rigid bodies. In other words, in the grommet 1 and the wire
harness 2, a structure can be easily realized in which the
protector side protruding portion 21e and the outer side protruding
portion 36 are arranged along the second width direction and the
wall surface on the border between the first grommet body side
recess portion 11l and the second grommet body side recess portion
11m is sandwiched therebetween.
[0108] Further, according to the grommet 1 and the wire harness 2
described above, the outer 30 has the body portion 31 formed along
the first width direction perpendicular to the pressing direction
and sandwiching the grommet body 10 and the protector 20 between it
and the water stopped surface 105 and the fixing portions 32 and 33
provided as a pair so as to sandwich the grommet body 10 with
respect to the first width direction and provided on both end
portions of the body portion 31 with respect to the first width
direction, the outer side protruding portion 36 is provided on each
of the fixing portions 32 and 33, and the protector side protruding
portion 21e and the first grommet body side recess portion 11l are
situated between the outer side protruding portion 36 and the body
portion 31 in a state in which the grommet body 10 is fixed to the
door panel 101 by the outer 30. Therefore, in the grommet 1 and the
wire harness 2, the protector side protruding portions 21e and the
first grommet body side recess portions 11l are situated between
the outer side protruding portions 36 and the body portion 31 in a
state in which the grommet body 10 is fixed to the door panel 101
by the outer 30. In other words, in the grommet 1 and the wire
harness 2, the outer 30 can be attached to the grommet body 10 in
such a way that the part of the grommet body 10 where the protector
side protruding portion 21e is fitted is surrounded by the body
portion 31 and the outer side protruding portion 36 of the outer
30. As a consequence, in the grommet 1 and the wire harness 2, the
grommet body 10 can be positioned on the door panel 101 and fixed
after surely positioned with respect to the outer 30.
[0109] Further, according to the grommet 1 and the wire harness 2
described above, the grommet body 10 has the insertion opening 11i
through which the protector 20 is insertable into the accommodation
space portion 11c from one side, and the protector 20 has the
positioning abutment portion 21f that is allowed to abut on the
inner part on the side opposite to the insertion opening 25 of the
grommet base portion 11c in a position where the protector side
protruding portion 21e is fitted in the first grommet body side
recess portion 11l. Therefore, in the grommet 1 and the wire
harness 2, by inserting the protector 20 up to the position where
the positioning abutment portion 21f abuts on the inner part of the
accommodation space portion 11c when the protector 20 is inserted
into the accommodation space portion 11c, the protector side
protruding portion 21e which is difficult to view since it is
situated on the side of the accommodation space portion 11c can be
surely fitted in the first grommet body side recess portion 11l. As
a consequence, in the grommet 1 and the wire harness 2, fitting of
the protector side protruding portion 21e into the first grommet
body side recess portion 11l can be facilitated, so that the
assembly workability when the protector 20 is assembled to the
grommet body 10 can be improved.
[0110] According to the grommet 1 described above, the grommet body
10, the outer 30 and the protector 20 as the rigid body portion are
provided, and the outer 30 has the fixing portions 32 and 33
provided as a pair so as to sandwich the grommet body 10 with
respect to the first width direction perpendicular to the pressing
direction and is fixed to the door panel 101 through the pair of
fixing portions 32 and 33.
[0111] According to the wire harness 2 described above, the
electric wires 3 where the connectors 4 are provided on the end
portions and the above-described grommet 1 are provided, and the
outer 30 has the fixing portions 32 and 33 provided as a pair so as
to sandwich the grommet body 10 with respect to the first width
direction perpendicular to the pressing direction and is fixed to
the door panel 101 through the pair of fixing portions 32 and
33.
[0112] Therefore, in the grommet 1 and the wire harness 2, the
outer 30 has the fixing portions 32 and 33 provided as a pair so as
to sandwich the grommet body 10 with respect to the width direction
and is fixed to the door panel 101 through the pair of fixing
portions 32 and 33 in a state in which the grommet body 10 is
sandwiched between the outer 30 and the water stopped surface 105.
That is, in the grommet 1 and the wire harness 2, with respect to
the direction (the first width direction, the second width
direction) perpendicular to the pressing direction, the fixing
portions 32 and 33 never lap over, that is, interfere with the
grommet body 10 and the protector 20. In other words, in the
grommet 1 and the wire harness 2, the fixing portions 32 and 33 are
situated outside the contours of the grommet base portion 11 and
the protector 20 in order not to lap over the grommet base portion
11 of the grommet body 10 and the protector 20 with respect to the
direction perpendicular to the pressing direction. And in the
grommet 1 and the wire harness 2, the grommet body 10 and the
protector 20 can be fixed to the door panel 101 through the fixing
portions 32 and 33 disposed in the positions as mentioned above in
a state in which the grommet base portion 11 and the protector 20
are sandwiched between the body portion 31 of the outer 30 and the
water stopped surface 105. Thereby, in the grommet 1 and the wire
harness 2, for example, even when the configuration (for example,
dimensions in the width and height directions) of the neighborhood
of the grommet attachment position on the side of the door panel
101 differs among vehicle models or the like, by changing the
configurations of the fixing portions 32 and 33 of the outer 30 or
the like structured separately from the grommet body 10, the
grommet body 10 can be appropriately fixed to the door panel 101
without the overall configuration of the grommet 1 being changed.
As a consequence, in the grommet 1 and the wire harness 2,
versatility can be improved. That is, in the grommet 1 and the wire
harness 2, for example, it is possible to make the structures of
the grommet body 10 and the protector 20 common to different
vehicle models while designing the outer 30 for each vehicle model.
Moreover, in this case, in the grommet 1 and the wire harness 2,
since the outer 30 is structured separately from the grommet body
10, the protector 20 and the like, the degree of freedom of the
positions where the fixing portions 32 and 33 are provided can be
improved, and the positions can be comparatively freely set
according to the shape of the side of the door panel 101.
[0113] Moreover, in the grommet 1 and the wire harness 2, since the
fixing portions 32 and 33 for bolting are placed on both sides of
the grommet body 10, for example, the fixing portions 32 and 33 can
be prevented from being hidden by the grommet body 10 and the like
when the outer 30 is fixed, so that bolting can be performed while
the fixing portions 32 and 33 are viewed. As a consequence, in the
grommet 1 and the wire harness 2, the workability at the time of
electric wire laying can be improved. Moreover, in the grommet 1
and the wire harness 2, since the fixing portions 32 and 33 are
fixed by the fastening bolts 32b and 33b, for example, compared
with a case where a clamp structure is used for the fixing portions
32 and 33, detachment from the door panel 101 is easy, and
re-attachment to the door panel 101 is also easy. As a consequence,
in the grommet 1 and the wire harness 2, maintainability and
serviceability of the vehicle 100 can also be improved.
[0114] Further, according to the grommet 1 and the wire harness 2
described above, the pair of fixing portions 32 and 33 are situated
outside the lip portion 13 with respect to the first width
direction in a state in which the grommet body 10 is fixed to the
door panel 101 by the outer 30. Therefore, in the grommet 1 and the
wire harness 2, the area which is positioned inside (between) the
pair of fixing portions 32 and 33 with respect to the first width
direction and which requires water stopping can be limited and made
relatively small. Thereby, in the grommet 1 and the wire harness 2,
the overall length of the lip portion 13 (the outside lip portion
13a, the inside lip portion 13b) situated inside the pair of fixing
portions 32 and 33 can be made relatively small. As a consequence,
in the grommet 1 and the wire harness 2, the outer shapes of the
grommet base portion 11 of the grommet body 10 and the protector 20
can be made relatively small, so that the size of the grommet 1 can
be reduced.
[0115] Further, according to the grommet 1 and the wire harness 2
described above, at least a part of the lip portion 13 is placed in
an area within the pressed region 35 pressed by the outer 30 and
between the pair of fixing portions 32 and 33 with respect to the
first width direction. Therefore, in the grommet 1 and the wire
harness 2, since the pressing force can be substantially uniformly
applied to the lip portion 13 in a comparatively wide area by the
lip portion 13 being placed in the pressed region 35 pressed by the
outer 30, water can be surely stopped between the water stopping
surface 11f and the water stopped surface 105 by the lip portion 13
pressed against the water stopped surface 105, so that water
stopping performance can be improved. More specifically, in the
grommet 1 and the wire harness 2, since a part of the lip portion
13 is placed in the area between the pair of fixing portions 32 and
33 where the force of pressing by the outer 30 tends to be
comparatively high, a larger pressing force can be appropriately
applied to the lip portion 13, so that water stopping performance
can be further improved.
[0116] Moreover, in this case, in the grommet 1 and the wire
harness 2, since the lip portion 13 is hollow and elastically
deformed with ease, for example, compared with a lip portion that
is dense inside, the lip portion 13 can be crushed so as to be in
contact with the water stopped surface 105 with a smaller pressing
force. As a consequence, in the grommet 1 and the wire harness 2,
since the reaction force that the outer 30 receives from the lip
portion 13 can be suppressed to a relatively small one when the lip
portion 13 is pressed, for example, even when the outer 30 is
formed of a resin material having rigidity lower than that of
metal, strength sufficient for receiving the reaction force can be
ensured. That is, in the grommet 1 and the wire harness 2, since
the outer 30 can be formed of a resin material has relatively low
rigidity, for example, weight increase can be suppressed, and even
when the outer 30 differs among vehicle models, manufacture is
easy.
[0117] According to the grommet 1 described above, the grommet body
10, the protector 20 and the outer 30 are provided, and the
protector 20 has the protector base portion 21 that forms the base
surface 21a of a shape along the water stopped surface 105 and the
protector cover portion 22 that forms the wiring space portion 23
where the electric wires 3 are passed between it and the protector
base portion 21 and forms the flat surface 22a where the weather
strip 104 provided on the door panel 101 across the grommet body 10
is placed with the grommet body 10 being interposed.
[0118] According to the wire harness 2 described above, the
electric wires 3 where the connectors 4 are provided on the end
portions and the above-described grommet 1 are provided, and the
protector 20 has the protector base portion 21 that forms the base
surface 21a of a shape along the water stopped surface 105 and the
protector cover portion 22 that forms the wiring space portion 23
where the electric wires 3 are passed between it and the protector
base portion 21 and forms the flat surface 22a where the weather
strip 104 provided on the door panel 101 across the grommet body 10
is placed with the grommet body 10 being interposed.
[0119] Therefore, in the grommet 1 and the wire harness 2, for
example, by pressing the lip portion 13 toward the water stopped
surface 105 by transmitting the pressing force from the outer 30 to
the lip portion 13 through the base surface 21a of the protector
base portion 21 while the electric wires 3 are protected by the
protector 20 accommodated in the grommet body 10, water can be
appropriately stopped at the gap with the water stopped surface
105. Further, in the grommet 1 and the wire harness 2, since the
surface where the weather strip 104 provided on the door panel 101
and the grommet body 10 abut on each other can be made flat by the
flat surface 22a of the protector cover portion 22, water can be
appropriately stopped at the gap with the weather strip 104. As a
consequence, the grommet 1 and the wire harness 2 can appropriately
deliver water stopping performance. That is, in the grommet 1 and
the wire harness 2, by situating the base surface 21a of the
protector base portion 21 as a rigid body inside the water stopping
surface 11f of the grommet base portion 11 as an elastic body, the
shape of the water stopping surface 11f can be made a shape along
the water stopped surface 105 by the base surface 21a of a shape
along the water stopped surface 105. Moreover, in the grommet 1 and
the wire harness 2, by situating the flat surface 22a of the
protector cover portion 22 as a rigid body inside the flat surface
11e of the grommet base portion 11 as an elastic body, the flat
surface 11e of the grommet base portion 11 can be made flat by the
flat surface 22a. As a consequence, in the grommet 1 and the wire
harness 2, the water stopping surface 11f together with the lip
portion 13 can be surely pressed toward the water stopped surface
105, and the surface where the weather strip 104 and the grommet
body 10 abut on each other can be made flat so that the weather
strip 104 is surely in close contact with the flat surface 11e of
the grommet body 10, so that water stopping performance can be
appropriately delivered.
[0120] More specifically, according to the grommet 1 and the wire
harness 2 described above, the protector 20 in which at least the
protector cover portion 22 and a part of the protector base portion
21 are interposed between the outer 30 and the lip portion 13 with
respect to the pressing direction of the outer 30 forms a layer
structure together with the grommet body 10. In this example, in
the grommet 1 and the wire harness 2, the protector cover portion
22 and the end portion of the protector base portion 21 on the side
of the insertion opening 26 are interposed between the outer 30 and
the lip portion 13, and the protector cover portion 22 and the end
portion of the protector base portion 21 on the side of the
insertion opening 26 are pressed toward the water stopped surface
105 by the outer 30.
[0121] Therefore, in the grommet 1 and the wire harness 2, even in
a state in which the electric wires 3 are passed in the wiring
space portion 23, by the outer 30 pressing the protector cover
portion 22 and the end portion of the protector base portion 21,
the protector cover portion 22 can be prevented from being lifted
from the protector base portion 21. Thereby, in the grommet 1 and
the wire harness 2, the flat surface 22a of the protector cover
portion 22, and thus the flat surface 11e of the grommet base
portion 11 can be surely maintained flat, so that water can be more
surely stopped at the gap with the weather strip 104. As a
consequence, in the grommet 1 and the wire harness 2, water
stopping performance can be improved. Further, in the grommet 1 and
the wire harness 2, the pressing force from the outer 30 is
transmitted to the protector base portion 21 through the grommet
body 10 and the protector cover portion 22, so that the lip portion
13 can be pressed by the base surface 21a of the protector base
portion 21. Thereby, in the grommet 1 and the wire harness 2, the
pressing force from the outer 30 can be more uniformly transmitted
to the lip portion 13, so that the water stopping performance in
the entire part of the lip portion 13 can be made substantially
uniform. In the grommet 1 and the wire harness 2, water stopping
performance can be improved also in this regard.
[0122] Further, according to the grommet 1 and the wire harness 2
described above, the protector 20 has the reinforcing wall portion
27 interposed between the protector base portion 21 and the
protector cover portion 22 with respect to the pressing direction
of the outer 30. Therefore, in the grommet 1 and the wire harness
2, since the protector 20 is reinforced with respect to the
pressing direction by the reinforcing wall portion 27 and strength
can be ensured, when a pressing force acts on the protector 20 from
the outer 30, the protector 20 can be made difficult to
collapse.
[0123] Further, according to the grommet 1 and the wire harness 2
described above, the reinforcing wall portion 27 includes the pair
of base portion side wall portions 27a provided on the protector
base portion 21 and opposing each other with an interval
therebetween with respect to the first width direction
perpendicular to the pressing direction and the pair of cover
portion side wall portions 27b provided on the protector cover
portion 22 and opposing each other with an interval therebetween
with respect to the width direction, the pair of base portion side
wall portions 27a and the pair of cover portion side wall portions
27b are arranged such that the base portion side wall portions 27a
contact the respective cover portion side wall portions 27b,
respectively. Therefore, in the grommet 1 and the wire harness 2,
when the pressing force acts on the protector 20 from the outer 30,
since the protector 20 can be prevented from being collapsed to be
deformed along the first width direction by the base portion side
wall portions 27a and the cover portion side wall portions 27b
contact each other, respectively, the protector 20 can be made more
difficult to collapse.
[0124] The grommet and the wire harness according to the
above-described embodiment of the present invention are not limited
to the above-described embodiment, and may be modified variously
within the scope of the claims.
[0125] While the lip portion 13 includes the outside lip portion
13a as the first lip portion and the inside lip portion 13b as the
second lip portion in the description given above, the present
invention is not limited thereto. The lip portion 13 may have a
structure not having either one of the outside lip portion 13a and
the inside lip portion 13b, or may have a structure having a third
lip portion. The configurations of the outside lip portion 13a and
the inside lip portion 13b are not limited to the above-described
ones. For example, the outside lip portion 13a may be inclined with
respect to the first width direction within the range of the
pressed region 35 pressed by the outer 30. In this case, as
illustrated by the chain double-dashed lines in FIG. 16, the
outside lip portion 13a' is formed so as to be inclined from the
vehicle interior space side toward the vehicle exterior space side
from the upper side toward the lower side in the vertical direction
(first width direction) within the range of the pressed region 35.
By providing this structure, the outside lip portion 13a' can guide
water drops trying to enter from the vehicle exterior space side,
from the vehicle interior space side to the vehicle exterior space
side. The inside lip portion 13b may be formed, for example, so as
to extend from the edge portion on one side to the edge portion on
the other side of the water stopping surface 11f in the first width
direction while a central portion in the first width direction is
bent so as to protrude toward the side opposite to the outside lip
portion 13a. In this case, the inside lip portion 13b may be
placed, for example, so that the bent portion side in the center is
situated within the placement region 104a of the weather strip 104
and that the edge portion side is situated within the pressed
region 35. Moreover, it is unnecessary that the entire part of the
outside lip portion 13a be situated within the range of the pressed
region 35.
[0126] While the protector 20 constitutes a rigid body portion in
the above description, the present invention is not limited
thereto. The grommet 1 may have a structure in which the protector
20 is not provided and instead of this, two-color molding is
applied by a high rigidity material to a predetermined part of the
grommet base portion 11 of the grommet body 10, that is, to a part
interposed between the outer 30 and the lip portion 13 and the part
having undergone the two-color molding constitutes the rigid body
portion.
[0127] While the outer 30 is formed of a synthetic resin material
in the above description, the present invention is not limited
thereto; for example, it may be formed of a metal.
[0128] While the outer 30 is bolted at the fixing portions 32 and
33 in the above description, the present invention is not limited
thereto; for example, it may be fixed to the door panel 101 by
clamping at the fixing portions 32 and 33.
[0129] Moreover, the connection portions of the wire harness are
the connectors 4 in the above description, the present invention is
not limited thereto; they may be terminals or the like provided on
the end portions of the electronic wires by crimping, welding or
the like.
